Large luggage space needs to be reserved on Shinkansen

Just saw this news (only in Japanese) about tourist taking up large luggage space in Shinkansen. Luggage measuring over 160cm needs to get a luggage reservation. Reservation is free and can be done when purchasing the Shinkansen ticket.

It seems like tourists without reserving a space is taking up all the large luggage reservation space.
